jbug genomic fragment lacking the second transcriptional start site (deletion of 2L:22725543-22727564 ;22729274-22729816 (R6)). Sequence for a GFP tag is inserted into the sixth coding exon 6 (same location as in jbugGFP). It results in expression of GFP-tagged jbug proteins from transcripts RF, RL and RN and the expression of untagged protein from transcript RM under native control.
jbugMGcDs.GFP can rescue the wing blister phenotypes of alleles of the moa complementation group.
